In August, several civil liberties groups filed a complaint that asked the U.S. Federal Communications Commission to investigate law-enforcement use of cell site simulators, or so-called Stingrays. The complaint was specifically leveled at the Baltimore Police Department for possibly violating the Communications Act and for using a technology that disproportionately affects minority communities.

On Thursday, 12 U.S. Senators followed up with an open letter to FCC Chairman Thomas Wheeler expressing concern about the use of Stingrays, together with a set of 10 detailed questions about the FCC’s role in overseeing the technology.

“We are particularly concerned about allegations that cell site simulators … disrupt cellular service and may interfere with calls for emergency assistance, and that the manner in which cell site simulators are used may disproportionately impact communities of color,” the senators wrote. 

The letter received applause from Georgetown Law Prof. Alvaro Bedoya, a former staffer of one of the letter’s signatories, Sen. Al Franken, D-Minn. "This is the right call from Senator Franken,” Bedoya said in comments provided to The Privacy Advisor. “Surveillance doesn't affect everyone equally. It disproportionately affects people of color, low-income people, immigrants, and other vulnerable communities. We need to see that surveillance isn't just about privacy. It's about civil rights and equal protection, too."

Indeed, the use of such technology also raises larger societal concerns, according to Justice First Director of Field Operations Eugene Puryear. "While it is clearly a positive step that a group of lawmakers are raising questions about stingray technology and its potential discriminatory impact, the very fact that there are so many outstanding questions and such a lack of transparency is in and of itself troubling. It is undeniable that racial profiling of various forms is central to law enforcement at every level." 

Stingray technology allows law enforcement to intercept mobile phone traffic by mimicking a cellphone tower. The method is similar to "man-in-the-middle" attacks, in that it captures the data between two legitimate cell phone towers.

"The impact, then, of technology with the ability to gather large amounts of information on the movements of large numbers of individuals heavily concentrated in particular communities raises a very clear risk of serious abuse," Puryear added. "In general we should move away from stingrays being used as a law enforcement tool, their implications in terms of the ability to construct detailed profiles of potentially thousands of people in a given area creates far too much risk of that same information being used against particular communities where, again, we know already racial profiling and biased law enforcement practices exist." 

The senators' letter, in part, stems from the complaint filed by the American Civil Liberties Union and others, from last August, which alleges the use of Stingrays violates the Communications Act because the surveillance technology disrupts the ability of cell phones to make or receive calls – including 911 emergency calls. This “willful” interference with a cellular network violates Section 333 of the Communications Act, the complaint argues. The ACLU also stated that local law enforcement have not gained appropriate licenses to operate Stingrays on the wireless spectrum.

The second prong of the senators’ letter, however, concerns the disproportionate use of the technology in minority neighborhoods. The senators point out that Section 151 of the Communications Act requires that FCC ensure U.S. citizens have equal access to communications technology, regardless of race, national origin, religion, or gender.

The August complaint included an image demonstrating the disproportionate use of Stingrays in minority neighborhoods. It was also tweeted by Bedoya.

Also in August, Georgetown University's Institute for Public Representation Director Laura Moy said, "There's a pattern of law enforcement agencies around the country engaging in racially discriminatory policing, and that extends to surveillance technology." She also believed Stingray use violates the Communications Act. "I think it's a pretty clear violation, and I think the FCC has been looking the other way for a long time, hoping nobody will notice." 

Thursday's letter was signed by Franken as well as Sens. Patrick Leahy, D-Vt., Ron Wyden, D-Ore., Sherrod Brown, D-Ohio, Edward Markey, D-Mass., Elizabeth Warren, D-Mass., Jeffrey Merkly, D-Ore., Tammy Baldwin, D-Wisc., Bernie Sanders, I-Vt., Tom Udall, D-NM, Martin Heinrich, D-NM, and Chris Coons, D-Del.. 

The senators point to a discrepancy in The Washington Post article linked above. "According to the Post article," they write, "an FCC official indicated that cell site simulators do not transmit signals on the wireless spectrum - a statement directly at odds with Department of Justice documentation on the devices." 

As a result, the senators are asking whether Stingrays transmit over frequencies used by traditional cell phone carriers. They also want to know whether law enforcement must obtain licenses from the FCC to transmit over the spectrum, and if so, what kind of oversight is in place; whether testing has been done in the real world to determine whether emergency calls would be affected; and whether a list exists laying out which law enforcement agencies possess the technology. The senators also inquire about whether the FCC's 2014 task force for assessing the misuse of surveillance technology has met or produced any results. 

The letter also touches upon another 2016 report in which the FBI allegedly asks state and local law enforcement agencies using Stingrays to sign a non-disclosure agreement. 

Though it's not clear whether the FCC's Wheeler will provide answers to the senators, or whether such an answer will be made public, it's tough to imagine any answers will be forthcoming anytime soon: The FCC just released a highly anticipated broadband consumer privacy proposal that is due for a vote by its commissioners later this month.

    There was no "other side" to this story? I find it hard to believe that there is no one on the other side of an issue like this.
    
    This article did not even describe the (allegedly) discriminatory actions that were taken by law enforcement agencies in this case. Worse, there is no explanation regarding exactly how those "vulnerable" communities are having a disproportionate effect visited upon them. Finally, the article repeats one perspective on a hotly contended issue (i.e., that law enforcement agencies around our nation routinely engage in a pattern of racially discriminatory practices) without any support and without any counterbalance.
    
    I would like to believe that our own professional organization (a) is nonpolitical, and (b) has enough faith in its members' intelligence to present multiple perspectives on politically charged issues and allow us to make up our own minds.

    If you want to prevent your phone from being scanned by stingrays, I would suggest using some sort of Faraday cage product.
    
    I certainly have nothing to hide, but I also want to keep my privacy and make sure my sensitive information is secure.  We see powers abused routinely in this country.
    
    That said, I use a leather Faraday cage product from these guys.  One of my buddies at the DoJ turned me onto it:  https://silent-pocket.com/collections/faraday-cage-products/products/sleeve-full-shielding?variant=1023876636

    Thanks, Jeff, for the feedback. This is a continuing news story that's been developing in recent months and this letter written by 12 U.S. senators to the FCC is clearly a new development. Further, the ACLU's extensive report on Baltimore PD's use of stingrays is a relevant data point, enough so that it prompted the senators to make the inquiry. I cannot fully excavate everything in that report in my article; there are only so many words I can put to paper before it turns into something that's too long to digest. The link to the ACLU report, however, is there for anyone who wants to dive in further and make their own conclusions about this issue.
    
    I hope the FCC will provide answers to the senators' questions, and I will certainly report on those answers as well.
    
    In considering your comment, I agree a comment from the FBI, DoJ or other law enforcement agency would have served this article. Alvaro Bedoya and Eugene Puryear are vocal about their concerns with this issue and they responded to my inquiry very quickly. It is often harder to get a quick response from government agencies.
    
    We take our reporting very seriously and will continue to do so. Thanks for reading.
